Subjective experiments were conducted to evaluate the effect of a streamer plasma air purifier
on perceived air quality, SBS symptoms and performance of office work during 5-hour
exposure of 32 recruited subjects in field laboratory in which real materials were used to
establishing a realistic level of air pollution. Intensity of SBS symptoms were indicated using
visual-analogue scales. Subjects’ performance was evaluated with several computer tasks.
The results show that operation of the air purifiers improved perceived air quality and reduced
the odor intensity of indoor air. Eye dryness symptom was found significantly improved when
the air purifiers were used but no other SBS symptoms or performance of office work were
improved when the air purifiers were in operation compared to the condition when they were
off.
